Lubricants act as anti-friction media and help in reducing the wear of the components in contact during the motion of the machine parts. Around the globe, petroleum-based reserves are going to deplete, which could result in a price hike and create concern about environmental pollution. This study examines reprocessing used SAE 15W-40 CI-4 lubricants into used lubricating oil that can be used for low-speed lubricants. SAE 15W-40 CI-4 used lubricant oil that has been used in car engines has changed physical and chemical properties, which contain water from burning fuel, metal wear particles, soot, and oxidizing lubricants such as sludge and corrosive acids. The research method used to separate impurities contained in SAE 15w-40 CI-4 used lubricating oil is by adsorption process and testing of several types of engine lubricants namely DEO API CI-4 SAE 15W-40, PCMO API SN SAE 10W-40, MCO API SL SAE 10W-30, HO ISO VG 32, TO API TO-4 SAE 10W with viscosity and additives, using the ASTM test method, for the index viscosity test (ASTM D2270), Pour Point (ASTM D97) and Flash Point (ASTM D92). The results showed that the higher the class of raw materials used for the manufacture of lubricants, the better the quality of the lubricant that includes the index viscosity, pour point, and flashpoint.
